It also consists of other novel features of i construction, all as willbe hereinafter fully set forth.

In the drawings, 1 designates the verticallymovable rod of a hydraulicelevator, which passes through the usual stuffing box 2. Around thestuffing-box is a liquid-tight casing or receiver 3, which may beprovided with a cover 4, havingacentral aperture 5, through which theshaft 1 freely passes. Extending nearly to the bottom of the receiver 3or in any case substantially below the top of the stuffing-box 2 is atube 6, integral with or connected at its upper end to a spout 7. Thespout passes out of the side of the receiver 3 and may, if desired, beadapted to carry a vessel 8, as shown. The receiver may also be providedwith a gage 10, which, however, form no part of the invention.

The operation is as follows: Water is first introduced into the receiver3, so as to stand above the foot of the tube 6. The receiver is thenfilled with a lubricant, as oil, above the top of the follower of thestuffing-box 2 and so as to surround the shaft 1. It is obvious that therod will be efficiently lubricated and that any drops of iwater whichmay leak past the stuffing-box will fall through the lighter oil to thewater-level at the bottom of the receiver. It will also be seen that anyexcessof water will be ejected through the tube 6 and spout 7 and thatbecause 'of the water-seal no oil can thus escape.

drawing-off cock 9 and a' By extending the receiver 3 a substantialdistance below the top of the stufng-box 2 a settling-tank is providedfor any dirt or other foreign matter which may adhere to the rod and becarried down to the oil.

It w-ill be evident that various changes may be made by those skilled inthe art which will come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

By lubricating the rod by a surrounding body of oil in the manner showna small amount of oil is carried down into the packing in the box 2,whereby it is-kept moist, pliable, and water-repellant.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A lubricating device comprising a vertically-movable rod, astuffing-box through which said rod passes, a liquid-receiver inclosingsaid stuffing-box and extending a substantial distance above and belowthe opening thereof and means for automatically drawing olf the liquidfrom the lower portion of said receiver whereby a constant liquid-leveli is maintained therein.

2. A lubricating device comprising a vertically-movable rod, astuffing-box through which said rod passes, a liquid-receiver inclosingsaid stuffing-box and extending a substantial distance above and belowthe opening thereof, a tube extending nearly to the bottom of saidreceiver and having an opening below the plane of the top thereofwhereby a liquid may be automatically drawn from the bottom of saidreceiver and a constant level of liquid maintained therein.
